Bill Belichick and the Patriots announced Thursday they are mutually parting ways after 24 years.

Under Belichick’s leadership, the Patriots won six Super Bowls and made three more championship appearances. Belichick is widely recognized as the greatest coach of all time. He coached thousands of players in New England, including some who took to social media to react to his upcoming departure.

Below is a sampling of those players’ reaction, including posts from Tom Brady, Rob Gronkowski and Julian Edelman. Several of the team’s current players, including wide receiver Kendrick Bourne and nose tackle Davon Godchaux, also expressed their gratitude toward Belichick in their own tributes.
